Abstract:To improve cheese yarn quality，the process setting，use and maintenance of the capacitive Uster electronic yarn cleaner and automatic winder are introduced in detail by tracking the number of defects and broken ends of 100 km of cheese yarn rewounding.Through the investigation and optimization of the process unqualified items of the automatic winder ESPERO，it is pointed out that the process setting of electronic yarn cleaner should be carried out according to the actual yarn quality and customer requirements，the daily cleaning and maintenance of electronic yarn cleaner should be done well，and the double yarn clearance rate should reach 100%.The setting and inspection of the operating interface，the operating parts of the equipments and the pressure of all parts of the winder should be done well.When the winding speed is not more than 1200 r/min，the tension of cheese yarn shall be based on the standard of non-adhesion and non-shelling during rewinding，so as to ensure that the large suction nozzle have no air leakage，the distance between the large suction nozzle and the protective cover of the grooved drum shall be 3 mm~5 mm，and the negative pressure vacuum of the main engine shall not be less than －0.4 MPa.If the maximum number of continuous knots at one time is small，the number of broken ends of cheese can be reduced and the cheese quality can be improved significantly.
Key Words:automatic winder；cheese yarn；electronic yarn cleaner；cleaning passage；yarn defects；the number of broken ends；knot；yarn cleaner；big suction nozzle；splicer
